On Windows and Mac (and with certain backends on Linux), Blender would always appear to be playing back audio even if there was no timeline playback. This would sometimes prevent devices from going to sleep or going into lower power state modes when idling. For the affected audio backends, we now automatically close the audio backend after 30 seconds of inactivity. Pull Request: https://projects.blender.org/blender/blender/pulls/136845
